CNBC’s Jim Cramer said Wednesday that signs of excessive speculation are creeping back into the market, echoing patterns that previously led to painful losses for investors . “Remember what happened last year when speculative stocks took over the market,” the “Mad Money” host said, pointing to a wave of speculative companies that surged on hype before they ultimately capsized, taking their investors down with them. After a powerful broader market rally in recent weeks, Cramer said he believes enthusiasm may be starting to outpace discipline. “They think that anything they buy goes higher … They have lost all discipline and they are cocky,” Cramer said. That do-no-wrong mindset, he cautioned, is pushing money back into the same high-risk corners of the market that caused trouble before, specifically unprofitable nuclear power startups, quantum computing plays, and space-related stocks. Those themes have long-term potential, Cramer acknowledged. However, he said he’s concerned that many of the smaller, pure-play names lack viable business models today. For investors who nevertheless crave exposure to those industries, Cramer recommended owning shares in established companies that have complementary business lines and real earnings, rendering them less speculative. Nuclear energy is “not a great business,” Cramer contended, because building nuclear plants from scratch is costly and takes too long. He highlighted companies like Constellation Energy and GE Vernova as more credible ways to gain exposure, citing their experience and scale. Constellation Energy is a diversified energy provider with a strong nuclear fleet alongside hydro, wind and solar assets. GE Vernova builds gas turbines and grid infrastructure and has a nuclear joint venture with Japan’s Hitachi. For quantum computing, Cramer said the only “viable” businesses currently belong to larger firms such as software and computing giant IBM and industrial conglomerate Honeywell , rather than smaller companies that remain “science projects.” Meanwhile, Cramer said the space industry will be easier to gain exposure with the imminent IPO of Elon Musk’s SpaceX. Cramer reserved his sharpest criticism for those buying Allbirds . The former shoe company on Wednesday announced its plans to pivot its business to AI compute infrastructure, sending shares up an astounding 582% in the session to $16.99 a piece. The stock tumbled 36% Thursday, but still ended the day at $10.91 a share, well above its $2.49 closing price before the frenzy. Rather than place a bet on Allbirds — or NewBird AI, as it will be called — Cramer recommended investors look to formidable semiconductors like Nvidia , Taiwan Semiconductor and Intel to play the AI compute boom. “The bottom line is this one’s a speculative bridge too far,” he said.
